On the other hand, especially when the metal parts of large metal parts, hardenability difference, the speed of cooling of oil system heat treatment solution is slow, cooling performance is not enough, therefore can use the heat treatment solution of water system.But water system heat treatment solution cooling performance compared with oil system heat treatment solution is higher, therefore easily produces inhomogeneous cooling, likely hardening crack.
As the technology improving resistance to inhomogeneous cooling performance, there will be a known the quenching based on salt solution all the time.Salt solution does not have the steam film stage, therefore has high cooling performance and resistance to inhomogeneous cooling performance is high, hardening crack is few (with reference to non-patent literature 1).But, when salt solution is used as heat treatment solution, get rusty in this extremely short time within 1 hour after heat treatment, also remarkable to the corrosion of the equipment such as oil groove, therefore industrially substantially cannot to use.
Thus, propose and improve speed of cooling (with reference to patent documentation 1,2) by the water system heat treatment solution containing the mineral acids such as the organic acid such as formic acid or acetic acid, hydrochloric acid or sulfuric acid or their salt.
